Only TV I know that uses the motion controls is the new Samsungs "E" series, although I am not aware of any monthly fee that is charged for use of the Apps (I dont have this TV) - based on your friend.. the $90 a month might just be the cable bill..lol
This amazing new function reacts to movements made by your hands to perform tasks such as changing channels, selecting an app, or navigating through web pages.
Enjoy the convenience of logging onto your Samsung Apps automatically. With the built-in TV camera, this unique feature is able to automatically recognize your face so you don't have to type in your ID and password on the remote control.
Voice navigation responds to the sound of your voice so you can perform tasks such as turning on the TV, changing channels, and accessing apps without having to press a button. You can speak your commands directly to the TV or into the remote's built-in microphone.
